摘　　要：Kerr nonlinearity is an important resource for creating squeezing and entanglement in quantum technology.Here we propose a scheme for generating Kerr nonlinearity originated from an engineered non-Markovian environment,which is different from the previous efforts using nonlinear media or quantum systems with special energy structures.In the present work,the generation of Kerr nonlinearity depends on the system-environment interaction time,the energy spectrum of the environment,and the system-environment coupling strength,regardless of the environmental initial state.The scheme can be realized in systems originally containing no Kerr interaction,such as superconducting circuit systems,optomechanical systems,and cavity arrays connected by transmission lines.
